A wiping device is attached to this type of intaglio printing machine. This wiping device includes a wiping roller as a rotating body that is in contact with an intaglio cylinder and rotates so that the opposed peripheral surfaces move in mutually opposite directions, and a plurality of pad surfaces that contact the peripheral surface of the wiping roller. Each brush is provided with a doctor blade made of steel or the like, which is located on the roller rotation downstream side of the brush and has its tip facing the wiping roller. Of the ink supplied from the inking unit of the inking device to the intaglio surface, the excess ink transferred to the periphery of the recess as a pattern and adhering is wiped off by the wiping roller rotating in contact with the plate surface, Only the design is transferred to the paper. The wiping roller is rotated by being immersed in a cleaning liquid such as trichlene contained in the cleaning liquid tank, and the ink transferred to the wiping roller by the wiping is removed by the cleaning action of the cleaning liquid and the brush, and the wiping roller is wiped. The cleaning liquid carried by the rollers is scraped into the cleaning liquid by the doctor blade.

By the way, in the ink wiping by such a wiping device, if the contact pressure of the wiping roller with respect to the plate surface is too strong, the ink in the concave portion as a pattern is also scratched out, and the fine line cannot be printed.
On the other hand, if the contact pressure is too weak, excess ink will remain around the recesses and the line width of the image will widen, resulting in bleeding printing.
Alternatively, some ink is left on the entire surface of the non-pattern portion to cause large stains, so that it requires skill to adjust the contact pressure. Further, since the wiping roller has a change in roller diameter due to wear or thermal expansion, there has been the troublesomeness and difficulty of readjusting the contact pressure each time. Further, when several tens of minutes have passed from the start of printing, the wiping roller thermally expands (due to friction with the plate surface), so that the contact pressure becomes stronger and the print quality fluctuates.

Therefore, the applicant of the present invention has previously disclosed Japanese Patent Application Laid-Open No. 4-37.
In Japanese Laid-Open Patent Publication No. 542, there is proposed a wiping device that simplifies contact pressure adjustment and eliminates the need for a dedicated operator. This is because both ends of the wiping roller are axially supported by the inner hole of the eccentric bearing in which the shaft center on the outer peripheral side and the shaft center of the inner hole are eccentric, and when the outer peripheral side of the eccentric bearing is rotated, the wiping roller becomes an intaglio cylinder. In a wiping device that is attached to and detached from a hydraulic cylinder whose piston rod tip is pivotally attached to the outer peripheral side of the eccentric bearing, and concentric to the head side of the hydraulic cylinder, the movement along the axial direction is transmitted but the rotation is not transmitted. Equipped with a screw shaft screwed into a fixedly mounted screw bearing and a contact pressure adjusting motor that rotates the screw shaft, and a wiping roller is attached to and detached from the intaglio cylinder by the operation of a hydraulic cylinder. The contact pressure between the intaglio cylinder and the wiping roller can be adjusted by operating the contact pressure adjusting motor in the worn state.

Further, when the contact pressure adjusting motor 12 is rotated while the wiping roller 1 and the intaglio cylinder 4 are in contact with each other, the screw shaft 8 rotates and moves in the axial direction, and accordingly, the hydraulic cylinder 5 also moves and wiping is performed. The contact pressure between the roller 1 and the intaglio cylinder 4 can be adjusted. Although FIG. 1 shows the left side (operating side) of the wiping roller 1, the right side (driving side) of the wiping roller 1 is also equipped with a device having the same configuration as described above.

A detection signal from a torque sensor 21 provided in the drive system of the wiping roller 1 is input to the control device 20. The torque sensor 21 is a highly durable one that can detect the torque of the rotating shaft magnetically in a non-contact manner by utilizing the magnetostriction phenomenon.
It is connected to the reduction gear 24 on the drive motor 23 side and the gear shaft 25 on the wiping roller 1 side via a and 22b. still,
Reference numeral 26 in the drawing denotes a drive side frame in which a gear shaft 25 is rotatably supported through a bearing 27.

With this structure, after the wiping roller 1 and the intaglio cylinder 4 are in contact with each other, the contact pressure adjusting motor 12 is rotated to initially adjust the contact pressure between the wiping roller 1 and the intaglio cylinder 4. When printing is started, the wiping roller 1 receives rotation resistance due to friction with the plate surface, and accordingly, the gear shaft 25 receives torque and twists. The torque at the beginning of printing is detected by the torque sensor 21 and becomes the set torque value.

When the printing progresses and the appropriate contact pressure increases due to thermal expansion of the wiping roller 1 (the roller surface made of vinyl chloride resin thermally expands due to friction with the intaglio cylinder 4) or decreases due to abrasion. The torque of the gear shaft 25 increases or decreases correspondingly.

However, in the present embodiment, the torque sensor 21 detects the fluctuation of the torque, and the control device 20 sets the detected torque value based on the detected torque value from the torque sensor 21 when the contact pressure is appropriate. The contact pressure adjusting motor 12 is feedback-controlled so as to obtain the torque value. That is, when the contact pressure increases and the detected torque value increases, the contact pressure adjusting motor 12 is reversely rotated so that the detected torque value becomes the set torque value at the proper contact pressure, while the contact pressure decreases and the detected torque value increases. Is decreased, the contact pressure adjusting motor 12 is normally rotated so that the detected torque value becomes the set torque value at the time of proper contact pressure.
